“…The four HCH isomers differ in their susceptibility to microbial degradation. A number of laboratory and field studies have shown that the α-, γ-, and δ-isomers are readily mineralized by aerobic microorganisms ( ). β-HCH was found to be the most persistent isomer to microbial degradation under aerobic conditions.…”

“…(31) and Escherichia coli (7) have been isolated and described as possessing only the ability to transform ␥-HCH to 2,3,4,5,6-pentachloro-1-cyclohexene (␥-PCCH). In addition, ␣-HCH has been, like lindane, observed to degrade under aerobic conditions in soil (1,2), which subsequently was used as inoculum for isolating a ␣-HCH-degrading aerobe identified as Pseudomonas vesicularis (10). Recently, Nagasawa et al (20) reported the isolation from an upland experimental contaminated field (28) of a bacterial strain, classified as Sphingomonas paucimobilis SS86, which used ␥-HCH as the sole source of carbon and energy.…”

“…We cannot conclude from our experiments whether soil bacteria capable of degrading ␥-HCH are totally lacking or present at a very low frequency or whether the concentration of the chlorinated pesticide compound in agricultural applications remains too low to permit an effective selective pressure. For instance, previous reports demonstrate that a biodegradation activity was detected in some of the soils which had experienced higher concentrations of ␥-HCH (10,28). In these cases, the competent bacteria were successfully isolated, identified, and genetically investigated (11).…”

“…Biodegradation of a-HCH under aerobic conditions can proceed rapidly (Bachmann et al 1988;Huntjens et al 1988). However, soil samples contaminated with HCH-isomers taken from a wastedisposal site in The Netherlands, which were incubated as soil-slurries in end-over-end mixing systems, showed a much lower biodegradation rate (Rijnaarts et al 1990).…”
